T0 (LZZ whom t may con/cern,.-

Be it known that I, EDWARD BARTHOLO- MAY, a citizen of the UnitedStates, residing at Rochester, in the county of Monroe and State of NewYork, have invented new and `useful Improvements in Devices forFastening Gras-Pipes, of which the following is a specification.

The invention relates to an improvement in pipe-hangers and supportsdesignedi particularly for use in connecting supply-pipes with fixtures,as ceiling-beams, in dwellings.

The main object of the invention is the production of means arranged forremovable connection with the pipe and for adjustable connection with asuitable hanger-bracket designed to be secured to the fixture.

The details of structure will be described in the followingspecification, reference being had to the accompanying drawings, inwhich- Figure 1 is a perspective view of a hanger constructed inaccordance with my invention, a short length of pipe being shown inplace therein. Fig. 2 is a side elevation of the same, the bracket-plateand a portion of the arm being broken away. Fig. 3 is a transversesection through the bracket-arm.

Referring tothe drawings, my improved hanger comprises a bracket-plate1, preferably of thin metal, provided with suitable openings 2, designedto receive screws or other fastening means by which the bracket may besecured to the desired fixture. One end of the plate is provided with adepending flange 3, to which is secured the depending arm 4. The arm 4,which may be of any length desired, is preferably plane on its sides,but formed with V-shaped grooves 5 in its front and rear faces, wherebyto provide additional holding edges,- as will be hereinafter explained.

The hanger proper includes a bar 6 of a length greater than the width ofthe arm 4, formed with transversely-arranged openings 7, (shown indotted lines in Fig. 2,) so positioned that when the bar is in positionthe openings 7 are'in alinement with the sides of the arm 4, as clearlyshown in Fig. 1.

The hanger-strap comprises a metallic bar preferably round in sectionand centrally formed in a return-bend 8, the terminals of said bar beingprojected in parallel relation and threaded, as at 9. Immediatelyadjacent the bend 8 the two arms of the strap are curved to provide apipe-receiving bend 10, said strap being of such length and the bend 10so located that the pipe 1l when held therein may rest snugly againstthe front wall of the arm.

In use my improved hanger is secured to the desired fixture, aspreviously described. The terminals of the strap are passed through theopenings 7 in the bar 6 and secured therein by nuts 12 and the bend l()of said strap arranged to engage the pipe, as shown, it being understoodthat the nuts are tightened until the pipe 11 is securely clampedagainst the front face of the arm 4, in which position the bar 6 will besecurely clamped against the rear face of the arm.

In the tightening of the parts described the function of the V-shapedgrooves in the front and rear faces of the arm 4 is apparent, as saidgroves provide sharp edges on said faces of the arm to bite into thepipe and bar, respectively, under the clamping action of the parts, andthereby materially assist in holding the parts.

While I prefer that the strap be formed prior to its introductionthrough the bar 6, it is obvious that said strap may be formed withoutthe bend 10 and bent about the pipe after its introduction through theplate 6.

While I have shown the hanger as arranged for connection to an overheadfixture, it is obvious that it is equally applicable to a base or a sidefixture. A

It is equally apparent that the bar 6 and hanger-strap are adjustablelongitudinally of the arm 4 to provide for anydesired elevation orposition of the pipe.

Having thus described the invention, what I claim as new is 1. Apipe-hanger comprising a bracket adapted to be secured to a fixture andformed on opposite faces with V-shaped grooves, a pipe-supporting memberadjustable on said bracket, said member being provided with means fordrawing a pipe into binding engagement with the edges of one of saidgrooves. f

2. Apipe-hanger comprising a plate adapted to be secured to a support,an arm depending therefrom and formed in one face with alongitudinally-arranged V-shape groove, and

a pipe supporting member longitudinally adjustable on the arm andprovided with means for drawing a pipe into binding engagement with theedges of said groove.

3. A pipe hanger comprising an arm formed on one face with alongitudinally-extending V-shaped groove, and a pipe-supporting member,and means for drawing the pipe supported by said member into engagementwith the edges of said grooves.

4. In a pipe-hanger, a plate, an` arm depending thererom and formed witha longitudinally-arranged V-shaped groove, and a pipe-support comprisinga bar to engage the edges of one groove in said arm, and a hangerstrapformed of a single length of material and bent to provide parallelterminals, and means to secure said strap-terminals to said bar, saidmeans operating to force the bar into engagement with the edges oi saidgroove.

5. In a pipe-hanger, a plate, an arm dependin therefrom and Jformed withlongitudinall -arranged V-shaped grooves, a bar to engage the edges ofone of the grooves of said arm, and a hanger-strap formed of a singlelength oiV material and bent to provide parallel terminals, the barbeing formed with openingsy to receive said terminals and nuts to engagesaid terminals and adapted to draw the pipe and the bar into engagementwith the edges of said grooves.

In testimony whereof I ajX my signature in presence of two witnesses.

EDWARD BARTHOLOMAY.
